Effector. Definition. noun, plural: effectors. (biochemistry) A molecule that binds to a protein and affects the function of that protein. (physiology) An organ, a gland, or a muscle that can respond and becomes active in response to a stimulus (e.g. nerve impulse).upplement. In biochemistry, an effector is that molecule that binds to a specific protein, and regulates the latter's biological activity. An effector molecule acts as a ligand that is capable of increasing or decreasing the activity of that protein.
In biology, an effector is an organ that reacts to the external  stimuli on receiving signals from the central nervous system. An  example is when the adrenal gland secretes â¦ adrenaline in response  to stress or danger.ecause allosteric regulators do not bind to the same site on the protein as the substrate, changing substrate concentration generally does not alter their effects. Of course there are other types of regulation as well. Active site inhibitors: An inhibitory factor may bind to and block the active site.
